24.6.4 On-Chip Connections
This section describes all on-chip interconnections of the GPTA0, GPTA1 and LTCA2
modules except the connections to I/O ports (see
Section 24.6.3 ).
24.6.4.1 Clock Bus Connections
The clock bus signals generated in the GPTA0 and GPTA1 clock distribution unit and
PLL clocks are interconnected between the GPTA0, GPTA1 and LTCA2 modules as
shown in
Figure 24-89 .
The GPTA0 clock bus drives Global Timers (GTs), Global Timer Cells (GTCs), and Local
Timer Cells (LTCs) of the GPTA0 module only. The GPTA1 clock bus drives its GTs,
GTCs, and LTCs
and the LTCs of the LTCA2 module.
Each GPTA0 and GPTA1 clock distribution unit has two pairs for PLL clock inputs, an
input pair for the local PLL clocks and an input pair for module-external PLL clocks. The
GPTA0 and GPTA1 modules are capable to use the PLL clocks from each other.
